RADIATOR.

Application led May 17, 19.534:l Serial No. 714,138.

This invention relates to improvements in radiators, and more particularly to radiators formed of sheet metal.

It is one of the objects of the present invention to provide a radiator formed of one or two sheets of metal pressed into the desired shape.

A further object of the invention is to provide a sheet metal radiator so constructed that the iiuid chambers will not bulge or spread when water or steam is forced therethrough.

A further object of the invention is to provide a sheet metal radiator in which a plurality of vertical fluid chambers on the same side of the central, longitudinal fluid conducting portions are formed from one integral sheet of metal.`

A further object of the invention iis to provide a radiator which is strong and durable, is Vinexpensive to manufacture, is of very simple construction, is neat and attractive in appearance, and is well adapted for the purpose described.

With the above and other objects in view, the inventionconsists of the improved radi ator, and its parts and combinations as set forth in the claims, and all equivalents thereof.

In the accompanying drawing in which the same reference characters represent the same parts in all of the views:

Fig. 1 is a longitudinal sectional view of Vthe improved radiator;

Fig. 2 is a fragmentary side view thereof Fig. is an end view thereof;

Fig. l is a fragmentary longitudinal sectional view of a modified form of the inveution; and f Fig. 5 is a view similar to Fig. l butshowing a second modified form of the invention.'

Referring now more particularly to the drawing, it will be seen that the numeral 8 indicates a radiator. rlhe radiator is formed of two sheets of metal 9 and 10, connected together at the ends, top and bottom, and welded along the lines indicated by the numerals 11, 12 and 13. The sheets 9 and 10 may be formed of steel, brass, or any other suitable form of sheet metal and each sheet is pressed into the desired shape, as shown in Fig. 1 to form coils 14; and longitudinally extending communicating conduits 15. The ends of the conduits 15 have secured therein threaded coupling members 16 to receive pipes (not shown).

Une of the particular objects of the invention is to prevent bulgingfor spreading of the radiator when steam or water `is forced therethrough and to that end various adjacent, intermediate portions of the radiator are secured together by riveting, spot welding, or any other suitable means. Referring to Fig. 1 it will be seen that the sides of each fluid chamber meet along a horizontal .line and said adjacent portions are riveted or spot Welded together at the points indicated by the numeral 17. Each vertical fluid chamber 14; may contain any desirable number of welded orriveted connections, and said connections are spaced at suitable intervals in a vertical row, corresponding tothe position of the connections 17 shown .in Fig. 1. f

The sheets 8 and 9 forming 'the radiator. also meet at various points along a central line and to prevent separation of said portions of the radiatorl similar welded or riveted connections 18 are provided. Thus, it will be seen that portions of the radiator are connected together to prevent bulging' thereof, but the radiator passageways are not shut off so as to prevent the free cireu lation of a fluid therethrough.

Fig. el illustrates a slightly modified form of the invention in which the radiator 8 is formed of sheets of metal 9 and 10 connected together and pressed to form vertical fluid chambers Llei. and communicating conduits 15. rlhe sides of the chambers .no .not curve inwardly but the ini er adja cent portions of the chambers meet along a central line. To prevent bulging, a vertical row of spaced sheets or strips of metal 19 are employed, the walls of the chambers being riveted or spot-welded thereto, as at 18 ln Fig. 5, a second modified form of the invention is shown wherein the sides of the coils lll of the radiator 8 do not converge. To hold the same together, vertical rows of spaced apart strips of metal 20 are used and the sides of the vertical fluid chambers are riveted or spot-welded thereto, as at 21. Other adjacent portions of the radiator are secured together as at 18".

From the foregoing `description it will be seen that -a radiator composed of two sheets of metal pressed into the desired shape is provided` and said radiator is constructed so that it will not bulge or give when a fluid is forced therethrough. Also,

the improved radiator is of very simple and novel construction, and is Well adapted for the purpose described.

llt/That I claim as my invention is;

l. A radiator formed of sheet metal and including vertical fluid chambers and eentral longitudinal Huid conduits, the depth ot the fluid chambers being greater than the distance between them, a plurality of the adjacent fluid chambers positioned on the same side of said fluid conduits being formed from one integral sheet oi metal, adjacent portions of said iuidchambers being secured together to prevent lateral and longitudinal spreading.

2. A sheet metal radiator designed to carry a predetermined pressure in a substantially reduced longitudinal sectional area comprising a radiator body formed with Vertical i'iuid chambers and central longitudinal iuid conduits but modified from standard practice for the same internal pres* sure by a substantial decrease in the distance between adjacent iiuid chambers and a substantial increase in the radiating area of each of said fluid chambers, opposite .poinv` tions ot' the fluid chambers being connected to provide against lateral andvlongitudinal spreading.

In testimony whereof, I atlix my signature.
